Sucking chest wounds require an emergency first aid solution that is fast, direct, and effective: the H&H Bolin Chest Seal (BCS) is specifically engineered to meet these critical needs.
The BCS is a sterile occlusive chest wound dressing for treating open pneumothorax and preventing tension pneumothorax that result from gunshots, stab wounds, or other penetrating chest trauma. The patented (US Patent No. 7,834,231) failure-proof triple-valve design of the BCS allows air and blood to escape while preventing the re-entry of either, thereby eliminating any unwanted gas or liquid exchange at the trauma site.
The large (6” diameter), rugged polyurethane disc structure of the BCS can cover practically any size chest trauma site. The temper of the disc prevents any disc wrinkling from occurring during application. In addition, the wound side of the disc is covered with a thick layer of jell-based adhesive, strong enough to not only seal over hair and blood but also flexible enough to be removed and reapplied to the trauma site if required.
In a recent evaluation, the Bolin Chest Seal performed superior to the Asherman Chest Seal in overall performance Read the report here.
Also, a 2013 study demonstrated that the Bolin Chest Seal was superior to an unvented/unvalved chest seal in managing a tension pneumothorax. Read more about this study here.
